ASTM F2009 – Standard Test Method for Determining the Axial Disassembly Force of Taper Connections of Modular Prostheses

This test method establishes a standard methodology for determining the force required, under laboratory conditions, to disassemble tapers of implants that are otherwise not intended to release. Some examples are the femoral components of a total or partial hip replacement or shoulder in which the head and base component are secured together by a self-locking taper.  The force required to disengage tapered joint is recorded.
